Scottish politicians behind a legal bid to cancel Brexit last night welcomed a victory in their battle to get their case heard by the European Court of Justice.

The group successfully appealed against a decision which saw their case rejected at the Court of Session.

As a result of their appeal the case will now be referred to the European Court of Justice which will determine whether the UK can legally revoke its Article 50 notification.

The group, which includes, Labour MEPs David Martin and Catherine Stihler and SNP MEP Alyn Smith – want the European Court of Justice (ECJ) to rule on the matter.

In order to do so, the politicians instructed lawyers to go to the Court of Session in Edinburgh to seek permission from that court to go to the ECJ.

Lawyers acting for the UK government argued that the arguments made by the politicians were “hypothetical” and “academic”.

They said the politicians arguments didn’t reflect the actual political situation and that European judges shouldn’t rule on the matter.

However, in a written judgement issued on Friday, Scotland’s most senior judge, the Lord President, Lord Carloway, and his colleagues Lord Menzies and Lord Drummond Young ruled in favour of the politicians.

After the judgment, SNP MEP Ross Greer said: “This sound judgement from the Court of Session paves the way for at least one bit of clarity amid the Tories’ Brexit chaos.

“It is entirely reasonable for us to ask whether the UK Parliament can revoke the triggering of Article 50 and end the Brexit process.

“We know that the UK Tory government, in the grip of Brexit extremists, has no intention of revoking Article 50 but that’s not the point.

“This is about ensuring MPs are fully informed of their options at this time of national crisis. If negotiations collapse, as appears to be happening, we have to know that a No-Deal disaster is not the only option on the table.”
